Naturalness that endures.

Viroc® is a composite panel consisting of a mixture of wood particles and cement called the Cement Bonded Particle Board (CBPB) offering a B1 fire rating. It combines the flexibility of wood with the strength and durability of cement, allowing a wide range of applications both indoors and outdoors. The production of Viroc® panel complies with the specifications of EN 634 and EN 13986 standards and carries the CE Marking Certificate.

The Viroc® panel has a heterogeneous appearance with different shades randomly dispersed, resulting from the natural colours of the raw materials used and the chemical reactions. Tone differences may be observed on the same face, between the faces of the same panel or between different productions batches.
